BRICK-HANDLING MACHINE.

Application filed September 19, 1913.

To all whom it may concern:

Be it known that I, EDMUND GU'RNEY, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in BriclcHandling Machines, of which the following is a specification.

This invention appertains to brick making machinery and comprises improvements in what are known as brick cutting tables.

The object of the invention has been to devise especially advantageous means for mechanically transferring a series of green or freshly cut brick from the cutting table to a suitable portable pallet upon which the brick may be readily carried 0H from the machine, either manually or by a suitable conveyer.

The invention utilizes certain principles of construction disclosed in my previous application, Serial Number 671,439, filed January 16, 1912, a pallet being utilized upon which the bricks are received, separated and moved, a stop or push board being arranged above the carriage supporting said pallet and being controlled to move in timed relation with respect to the carriage whereby at a predetermined time said stop will sweep the brick from the spreader pallet onto the portable or removable pallet that is carried off with the brick to the point of deposit where the latter are dried.

The invention resides particularly in the special means employed to control the operation of said stop or push board, an especially simple and compact arrangement of parts being devised and the action of the push board being rendered positive as well as readily susceptible of variation by adjustment of suitable means.

In the drawings:-Figure 1 is a side elevation of a conventional type of brick cutting table showing the improvements of the invention applied thereto. Fig. 2 is a front elevation illustrating more particularly the guide frame, the stop or push board mounted thereon, and the operating cables connected with the latter. Fig. 3 is a detall view of the trip lever and its arrangement in respect to the platen or bed of the cutting table which latter is movable with the carriage that controls the operation of the cutting mecha nism, dotted lines showing the range of Specification of Letters Patent.

movement of the trip lever. Fig. 4e is a fragmentary view showing more clearly the relatlve arrangement of the trip lever and the cooperating co-aXially mounted tripping arm. Fig. 5 1s a detail view of the trip lever alone. The cutting table illustrated in the drawngs is of a conventional type and while the invention is shown as applied thereto it is to be understood that by reason of the special construction of the various parts of the invention, the latter is adapted to be just as readily attached to and used in connection with many other types of cutting tables.

The numerals 1 denote the sides of the frame of the cutting table, and 2 designates a sliding carriage supported by suitable rollers 3 mounted on shafts 4L journaled in the frame in any suitable manner. The carriage 2 comprises a bed or platen 5 at one end of the same which is movable with the carriage as the latter is actuated back and forth in the operation of the machine. The means for operating the carriage 2 consists of a hand lever 6 mounted on an end of a shaft 7 which is journaled in the frame 1 of the machine and on which is fixed a pair of grooved segments 8. Cables 9 are attached at their outer ends to each side of the carriage 2 and at their inner ends to the adjacent one of the segments 8 and operate around the grooved portion of said segment, any lost motion being readily taken up by adjustment of nuts forming parts of the connections between the cables and the carriage.

Cutting mechanism comprising a cutter frame consisting of the curved arms 10 is pivotally supported upon the frame 1 of the machine and adapted to be given an oscillatory movement under the action of the carriage 2, the range of movement of the arms 10 being illustrated by the full and dotted lines in Fig. 1. The arms 10 are connected by a tension bar 11 with which the cutting wires 12 are connected by suitable tension nuts. An abutment 13 is supported by the frame of the machine and performs its customary function, as will be later described.

All of the construction just set forth is found in the conventional type of machine or cutting table with which my improvements are employed.

The present improvements reside in the provision of attaching parts including supporting arms 14 which are secured to the sides of the carriage 2 in any suitable manner. The arms 14 support near their inner ends a spreader pallet 15 of the kind fully described in my previous application above identified and which, not forming a part of the present invention, is not therefore described in detail. Said arms 14 are also adapted to support a portable or removable pallet 16 adapted to rest on the outer end portions of the arms and spaced from the pallet 15, there being a base board 17 that connectsthe arms 14- together. Also secured to the opposite sides of the frame of the machine and projecting upwardly therefrom is a guide frame consisting of the guiding standards 18 each composed of spaced members and being connected together by the horizontal bar 18 The stop or push board 19 is mounted with its ends adapted to slide between the spaced members of each standard 18. Cables 20 are connected with the member 19 near its ends, pass over pulleys 21 on the bar 18 and are connected together to form a single cable 20, the point of connection being located some distance from a sheave 22 supported at the upper end of one of the standards 18 and over which said cables also pass. The single cable 20 leads from the pulley 22 over a pulley 23 on the frame 1 and thence extends to a point of connection with an adjustable eye-bolt 24 on the lower end of the trip lever 25. The lever 25 is pivotally mounted on the frame 1, being directly supported by a bracket 26, and the lower end of said lever is slotted longitudinally at 25 to admit of a certain amount of adjustment of the connection 24 whereby to control a slight variation in the timing of the relative movements of the carriage 2 and stop or push board 19. On the bracket 26 is also mounted a trip arm 27 having a weight portion 27 at its lower end, the latter being engageable with the lug 25 off-standing from the lever 25.

It being noted that the upper end of the trip arm 27 is in the path of movement of the platen 5 before mentioned, the operation of the machine in conjunction with the improvements above described will be understood fully from the following description. lVe shall assume that the parts are in their full line positions as illustrated in Fig. 1, and that the lever 6 has just reached its illustrated position thereby causing the cutting wires 12 to out the stick of clay previously fed onto the platen 5 into a series of bricks. On now moving the lever 6 to the right it will be apparent that the cut bricks which have just previously been shifted from the platen 5 onto the spreader pallet 15, will be carried to the right, moving between and beyond the guide standards 18. At the beginning of the rightward stroke of the lever 6, however, the platen 5 impinges with the trip arm 27, tilting said arm and with it the interlocked lever 25, to the dotted line position shown in Fig. 1 and in Fig. 3. Such movement of the lever 25 exerts a pull on the cables 20 and 20 and elevates the stop or push board 19 just before the bricks reach the same, thereby permitting the bricks to pass on beneath said board until they are beyond the same or substantially in the full line position in which they are shown at as in Fig. 1. the lever 6 carrying it leftward it will be apparent that the bricks just spread and resting on the pallet 15 will be swept from said pallet by the stop or push board .19, owing to the fact that the latter is dropped at the end of the rightward stroke of the lever 6 at which time the platen 5 has assumed the position shown in dotted lines in Fig. 3, permitting the restoration of the parts 25 and 27 to their normal vertical position. Thus it is that as the lever 6 starts to move leftward with the carriage 2 and supported parts the outer edge of the platen will simply strike the weighted arm 27 and tilt the same without afi'ecting in any way the position of the lever 25 and the stop board 19 connected with the latter. During this leftward movement of the lever 6 and the carriage 2 the action of the stop board 19 on the bricks transfers the latter, of course, to the portable pallet 16 ready to be carried off on said pallet, either manually or otherwise.

Having thus described the invention, what is claimed as new is:
